Product Details
The 3500/42M-01-01(140734-02+128229-01) Proximitor Seismic Monitor is a four-channel machinery protection module engineered by Bently Nevada. It continuously processes input signals from proximity and seismic transducers to measure vibration and position parameters. By comparing these live inputs against user-programmable alert and danger setpoints, the monitor drives rack relays to safeguard critical rotating machinery against unexpected mechanical failures.
Functional Overview & Measurement Capabilities
The module operates within a standard 3500 rack configuration and accepts 1 to 4 channels of sensor inputs. Each channel pair can be independently programmed via the 3500 Rack Configuration Software to monitor parameters such as radial vibration, thrust position, differential expansion, and acceleration. Conditioned static values are evaluated continuously to ensure immediate fault detection and reliable plant operation.
Hardware Configuration & I/O Architecture
This specific package combines the 140734-02 monitor module with the 128229-01 Prox/Seismic I/O module featuring internal terminations. The internal termination design streamlines field wiring connections directly at the rear barrier of the rack without requiring external termination blocks. The configuration includes cNRTLus hazardous area approval suited for Class 1, Division 2 environments.
